Ahmad - A CGM is nothing more than a tool that one can use to better control blood glucose levels. The most important variable in this equation is the person with diabetes. If that person is motivated to achieve better control then a CGM will go a long way toward delivering it.
Since you mention that you test your BG 8-10 times a day and even interrupt a night’s sleep to test then I believe you are highly motivated to improve your control!
I have found that whenever I follow my blood sugar closely and write it down then my control tends to improve. It is the awareness of my current blood sugar situation that engages me to to take action to influence the direction of my BGs.
The difference between finger-stick BG “snapshots” and the real-time full motion movie produced by a CGM is huge. CGMs add a critical dimension to BG monitoring: trends. This makes all the difference in the world. If you do a finger-stick BG before bed and read 120, you may conclude that you’re in good shape. But what if you knew that your BG was actually falling 2 mg/dl/minute? With that trend going on then you could be in hypoglycemia a half hour after falling asleep.
The other very important feature that a CGM contains is the ability to warn you of a steep rise or a steep fall as well as high or low levels. It’s nice to get a heads-up when your BG, currently at 90, is falling 3 mg/dl/minute. It gives you time to take action. Most people are easily distracted by life’s activities (as a graduate student you are preoccupied by a myriad of things, things that give meaning to your life and are important to you).
No one wants to be a “professional diabetic.” However, paying closer attention to your BGs using a continuous glucose monitor will give you the freedom to pursue important work without endangering your basic health. It’s counter-intuitive; the more you pay attention, the more freedom you gain.
Sorry for the long post. In short, I believe that you are an excellent candidate for a CGM and will most likely receive many benefits from it. I say, “Go for it!”
By the way, since I started on the Dexcom 7+ system, I have virtually eliminated lows below 55 and have been warned of every excursion below 80 so that I could take effective counter action at the right time. I’ve also markedly reduced the variability of my BGs. The data management system (I download the CGM data to a netbook computer.) I use reports to me a standard deviation number that tells me how variable my BGs have been.
